     12The figure above represents the standard ExoGENI iSCSI architecture using a shared vlan for access to iSCSI targets.  
     13 
     14The IBM DS3512 has 4 network ports.  In our configuration, two of the ports are connected to traditional VLAN ports of the data plan switch which is in hybrid mode. These ports are on vlan 1009.    
     15 
     16Virtual machines access iSCSI targets through an extra virtual NIC.  The extra NIC is connected to the OpenStack worker's 'storage' interface using existing Quantum NEuca mechanism for plumbing virtual networks.  The only difference is that the vlan is statically configured with tag 1009 using the storage interface. 
     17 
     18The ORCA controller is responsible for requesting the additional network interface and for assigning an IP within the correct subnet but not conflicting with any existing IP on that network (other VMs or the iSCSI device itself).  In addition, the ORCA controller must include information related to the iSCSI target so that it can be delivered to the NEuca tools withing the VMs (i.e. through the userdata mechanism).
